An elderly friend of mine has a Dick Smith Wizzard game console/PC, that had been sitting in his draw untouched for the last 15 or so years. I'm fairly positive it's all in working condition, because I think I was the last person to play it when I was around 6 years old! It looks immaculate and definitely has all the cables/power supply/manual/Cartridges/Tapes, unfortunately no box.

Does anyone know much about these, or has one? Are they rare and where could I get an item like this valued? It's a very cool piece of kit with all the iconic Dick Smith branding on it.
